地震二维归位问题和三维地震勘探

A DISCUSSION ON 2-D AND 3-D SEISMIC SURVEY

南海西部石油公司研究院

本文从理论上阐述了反射剖面与地层界面的空间关系,并以此为依据,用较多的实例讨论了二维地震解释中存在的问题,分析了由此造成的失误.与此同时,作者又从地质效果和经济效益方面,讨论了在复杂地质条件下的油气田勘探与开发中,三维地震勘探所起的重要作用.

In this paper, the spatial relations between the interfaces of formations and reflectors were set forth in theory. Problems appeared in 2-D seismic interpretation and causes of misinterpretation were discussed in line with what have been mentioned above with a lot of real examples. The important roles of 3-D seismic survey in oil/gas exploration and development in complex geology areas were also expounded from both aspects cf geological and economical effects.
